HDTV TELEVISIONS

The formats of the broadcasts are referred to using a notation describing:

* The number of lines in the display resolution.

* Progressive frames (p) or interlaced fields (i).

* Number of frames or fields per second.

For example, the format 720p60 is 1280 × 720 pixels, progressive encoding with 60 frames per second (60 Hertz known as Hz). The format 1080i50 is 1920 × 1080 pixels, interlaced encoding with 50 fields (25 frames) per second. Often the frame or field rate is left out. It can then usually be assumed to be either 50 or 60, except for 1080p which is only supported as 1080p24, 1080p25 or 1080p30 by consumer HDTV displays. A frame or field rate can also be specified without a resolution. For example 24p means 24 progressive frames per second and 50i means 25 interlaced frames per second. Most HDTV systems support some standard resolutions and frame or field rates.
